Subject: [RFC PATCH v2 12/12] powerpc/ptrace: move ptrace_triggered() into hw_breakpoint.c
Date: Fri, 28 Jun 2019 15:48:02 +0000 (UTC)	[thread overview]
Message-ID: <91218c7e0ea432e188c6d164097d383360f3c2e0.1561735588.git.christophe.leroy@c-s.fr> (raw)
In-Reply-To: <cover.1561735587.git.christophe.leroy@c-s.fr>

ptrace_triggered() is declared in asm/hw_breakpoint.h and
only needed when CONFIG_HW_BREAKPOINT is set, so move it
into hw_breakpoint.c
